My invention relates toiniprovementsjin sheathing paper, particularlyuseful as weather-proofing and water-proofing means,

adapted to be disposed across the woodwork 5 of stucco structures, priorto there'aga'inst of thelath and stucco 'composl tion.

I One of theobjects of the present invention is the provision ofsheathing paper having p binding strips atqspaced'intervals' securetransversely thereacross,lsaid strips adapted "for reinforcingthesheathing paper and for assisting it in resisting wrinkling :or'crushthrough which fastening nails, or.the.;like,

may be driven for temporarily securing the sheathingpapento'thewo'odwork, prior to the application thereto ofthemetallathand "stucco compositionl; a further obj set is the provision of bindingstrips relatively softer and more when a nail or other fasteningdevice'is projected therethroughi from the outer side, as I whenfastening the paper temporarily tothe woodwork of a structure,

lath thereto, the outer side. portion will, firstsoftan d pliablematerial, will remain in close bodily associationlwith the sides of theLnail or other fasteningidevice, thereby resisting any possible leakageof water through said outer'side portion along the sides of said nailsor 'fastening'devices' a still further object is the provision ofbinding strips formed 1 ing paper, saidstrips being thicker and softerthan the latter and beingadapted to function as a cushion against whichfurring elements are. forced .by i'the' drivi g the-fes 'j egainsttheexterior or face side Qf lGO the application pliable than the bodyofthesheath ing paper, whereby said paper, considering I said strips asforming part thereof, will have spaced areas of which the inner sideportions or in securing the 1y, resist any tearing of saidinn er sidepjortionby the drivingsof thenails'therethrough, secondly, the outerside portion, comprising 1 means of a fastening nail.

In applying furred metal lath to the plain commercial building paperheretofore used in stucco work, the furring devices were neces- 7 sarilydisposed directly against the body of the relatively thin paper, whichusually resulted-init-being torn 'by said devices as they were forcedthereagainst and thereinto by the .dri nggof t e fasten g nail,subjecting the weather-proofing, prior to the application thereagainstofthe stucco composition. The stucco composltlon is not shown 1n the Thebinding strips't, extend transversely-across the'face of the main bodyportion ofthesheathing-paper 1, preferably more .orcless at rightanglesavith the side edges thereof, and'rwhichzforman integral part 11thereof, are-intendedto be factory built I .thereonto; "preferably bycementing them v thereagainst. by means zof. a suitable adhesive paperatsuch damaged places to leakage, and thereby,' defeating the primarypurpose for e which sheathing paper is employed, namely, i paper, and atpresent generally'appliedto 15 .the wall boards of stucco structures asa to preventpwaterrfrom the exterior leaking through the paper to thewoodwork of the 80 structure.-
